Web Player: DynamicHeapAllocator out of memory

I am getting this error message (DynamicHeapAllocator out of memory - Could not get memory for large allocationCould not allocate memory: System out of memory!) for my Web build. It runs fine for Standalone, Android, and iOS builds; and occasionally works on FireFox. I came across this [thread][1], which sounds exactly like what I am experiencing; but there is no solution posted. I am using version 4.5.5. Any help or insight will be appreciated.
